Based on detailed study on structural characteristics and reservoir distribution of Taiyangdao-Kuihuadao fractured anticlinal structural belt, through analysis on gas type and genesis, this paper summarizes the geological rules of reservoir formation of this area so as to provide theoretical evidence for further exploration.

摘要在对太阳岛－葵花岛断裂背斜构造带构造特征和储层分布进行精细研究的基础上，通过对该区天然气类型和成因研究分析总结了该区成藏地质规律，为该区的进一步勘探提供了理论依据。

Aran anticline northwest dumping fractured reservoir development is the most favorable position.

Aran背斜的西北倾伏端是裂缝性储层发育最有利的部位。

Its shock waves spread through L'Aquila, shaking to the ground a hotel and several apartment blocks. They wrecked a university residence, trapping many students inside. The earthquake gashed solid 18th-century palazzi and shook the brickwork out of flimsy structures thrown up in the 1960s. Bridges and viaducts in the city, high up in the Apennine mountains that form Italy's backbone, were left perilously fractured.

震波穿过拉奎拉向四周传播，一家酒店和几个公寓住宅区被夷为平地；某大学宿舍区遭到破坏，多名学生被困其中；许多坚固的18世纪建筑出现了裂缝，多座建于20世纪60年代的建筑的脆弱墙体出现砌砖脱落；市内多座桥梁和高架桥断裂，这些桥梁曾连接亚平宁山区，是意大利的主干道。

Ordinarily only one cortex and the cancellous bone are remoed for grafts, and the fractured crest, along with the apophysis, is replaced in contact with the remnant of the ilium and is held in place with heay nonabsorbable sutures.

通常仅取一例皮质骨板及松质骨，然后将折断的髂嵴与骨骺一起进行复位，用粗的不吸收缝线缝合，固定于和残留髂骨相接触的位置上。

In children the physis of the iliac crest is ordinarily presered together with the attached muscles. To accomplish this, a cut is made parallel to and below the apophysis, and this segment is fractured in greenstick fashion at the posterior end.

在儿童，髂骨的骨骺通常与附着的肌肉一起予以保留，因此要在骨骺下方与其平行切开，并在髂嵴后方造成青枝骨折。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
